Rosacea is a skin condition that mainly affects the central face, and is often characterized by flare-ups and flushes. Although there is no cure for Rosacea yet, regular skin care in combination with lifestyle changes, can help control its signs and symptoms. Rosacea Diary helps rosacea patients to keep track of their daily skin care routine. Creating a daily track record can help patients to understand their progress in reducing the symptoms of the disease. Aside from various forms of flare-ups and remissions, rosacea often comes with an impact on patients’ social engagements, public contact or even work environments. With Rosacea Diary, users have a chance to track the application of various forms of topical and/or oral medication and their mood to potentially understand how a change in lifestyle as well as regular skin care affects their condition. Individuals who suspect they may have rosacea are urged to see a dermatologist or other qualified physician for diagnosis and appropriate treatment.
